Provide an EDID emulator that shall provide automatic and continuous EDID management for HDMI signal sources Shall provide the option to disable HDCP processing at the HDMI input connection when passing unencrypted content HDCP enable/disable function turns off the unit's HDCP capability. Some computers choose to encrypt their output even when non-protected content is displayed, such as desktop images or presentations. This function forces the source to send an unencrypted signal if the content itself is also unprotected. It therefore helps technicians to integrate such laptops into a non-HDCP AV environment. KVM Extenders enable the transmission of video data over long distances, whereas KVM Switches provide connectivity between multiple sources and one set of screen and peripherals or vice versa. Both technologies act as a connection intermediary between one or multiple video sources and displays. Most of the latest digital KVM devices support EDID exchange, yet some analog VGA KVM devices may require special attention and if necessary additional help from EDID Ghost Emulators (additional information below). If you’re using an HDMI switcher (through the receiver or otherwise) every time you switch it may reset the output settings from your video source, meaning you’ll have to go into your video source’s settings and manually reconfigure the video output resolution. Obviously, this is not optimal.

One more way problems manifest in the EDID loop is when using a switcher or receiver and experiencing a long delay when switching sources. Every step in the process has to take in the EDID signal, adjust, then output the right signal. First, the EDID version and manufacturer information of the screen is included (model number, serial number, etc.). Most importantly, the video resolution supported by the screen is also reported, so that the video source knows if it should be outputting a signal at 720p, 1080p, 4k, or something else entirely. In accordance with The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 we would like to make you aware of the following important information: Simplifying your setup as much as possible will be the first step to eliminating EDID issues. If you have a receiver that is sending signals to the Television, that’s one thing, but if you have cable extensions in your system, you’ll want to consider upgrading to longer cables that don’t need an extension. Testing: An EDID emulator can be used for testing and troubleshooting purposes. It can be used to test the compatibility between different devices or to verify that a device is correctly identifying the capabilities of a display.

If you’re running multiple video sources to a receiver, that’s a step where the EDID signal now has to go across the motherboard of the Receiver and come out the other side, to the output, intact, for your system to work properly. When monitor is connected to PC, there will be a conversation between them, ‘Hello, PC! I’m monitor A, I can display multiple resolutions. The max resolution I support is XXX” “Hello, monitor! I have received your information, I will output to you at the best resolution now.”

In the world of A/V, there are numerous standards, protocols, and different AV features that work based on them. And they keep evolving into a new generation for better performance and higher efficiency. And the EDID standard is so baked-in to modern video formats that it’s kind of hard for things to go wrong. There’s not a way you can “break” the EDID process because you’d have to be messing with the pins on the transfer cables, or modifying the hardware and code on the respective devices motherboards.

Restores +5 volt and HPD signals lost due to issues at the source or display, as well as faulty or long cables Another way this EDID information can be disrupted is if you’re using cable extensions that are on the cheaper side. A simple female-to-female HDMI adapter might allow you to extend your HDMI cables easily, but it may also strip or disrupt the EDID signal out, leading to the same issues described above. Or, if you’re using an HDMI Wireless setup, the same problems can occur. If you have a video source that has to go to a receiver or HDMI switcher, for instance, and then to a screen, you’re adding steps that the EDID process has to make it through before things will work properly. The item(s) are returned within 30 days of cancellation. The 30 days start the day after you have notified us of the cancellation Prior to the development of EDID, pins 4, 11, 12, and 15 on the VGA connector were sometimes used to define monitor capabilities. These ID bit pins carried either high or low values to define different screen resolutions. VESA extended this scheme by redefining VGA connector pins 9, 12, and 15 as a serial bus in the form of the DDC - Display Data Channel. This allowed for much more information to be exchanged, so that EDID and other forms of communication were possible between the source and the display.
